Little fun fact: if you are walking or running on treadmill ALWAYS try to make it at least a 2% incline to prevent shin splints!
On a flat treadmill, people often overstride.. landing heavily on the heels with the leg too far in front of the body. That extra impact repeatedly stresses the tibialis anterior (the muscle along the shin).
Always try to do a slight incline! Have you ever actually noticed how much better your legs feel walking at an incline? Was this helpful or did you already know this?!
